Namespace:  Microsoft.ApplicationServer.Caching
Assembly:  Microsoft.ApplicationServer.Caching.Client (in Microsoft.ApplicationServer.Caching.Client.dll)

public DataCacheItemVersion PutAndUnlock(
	string key,
	Object value,
	DataCacheLockHandle lockHandle,
	IEnumerable<DataCacheTag> tags
)

Parameters

key
Type: System..::..String
The unique value that is used to identify the object in the cache.
value
Type: System..::..Object
The object to add or replace.
lockHandle
Type: Microsoft.ApplicationServer.Caching..::..DataCacheLockHandle
The DataCacheLockHandle object that was returned when the object was locked.
tags
Type: System.Collections.Generic..::..IEnumerable<(Of <(<'DataCacheTag>)>)>
A list of tags to associate with the object.

Return Value

Type: Microsoft.ApplicationServer.Caching..::..DataCacheItemVersion
A DataCacheItemVersion object that represents the version of the cached object after it has been updated by this method.

Locked objects are never expired, but they may expire immediately if unlocked after their expiration time. For more information, see <maml:externalLink><maml:linkText>Expiration and Eviction</maml:linkText><maml:linkUri>http://go.microsoft.com/fwlink/?LinkID=193435</maml:linkUri></maml:externalLink>.

Tags may only be used to retrieve a cached object if that object is stored in a region. This overload does not store the object in a region.

If the lockHandle parameter is not equal to the DataCacheLockHandle object obtained from the method that is used to lock the object, a DataCacheException object is thrown with the ErrorCode property set to InvalidCacheLockHandle, and the object is not updated.
